What do driving practices have to do with vaccinations? Do you actually have any reason to think that the pro-vax population is more prone to unsafe driving practices? Or is your point that "in a large population, I bet I can find many people whose actions don't perfectly align with the principles they identify with"? Such a statement would be inane--it's been known for thousands of years that virtually nobody passes the test of totally consistent principled behavior (see Diogenes, who was "looking for a [truly principled / reasoning] man", and could find none).

Mandatory rules. Yours is a good question, but the parent’s suggestion might be totally fair. People in the US, and in other countries too, clearly have a problem with mandatory things, a lot of people are so determined to defy rules imposed on them, they will break the rules even when it’s in their interest to abide.
I have family members who, to this day, won't wear their seatbelt in their car because "the government has no business tellin' me what to do!" They know it is safer but won't do it out of petty spite. Orthodox Individualism is America's national religion.
